本発明は、電極形状に改良を加えてピード形状、溶込み
形状を改善しようとする非消耗電極溶接方法に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a non-consumable electrode welding method that attempts to improve the bead shape and penetration shape by improving the electrode shape.

あるが、開先の底面(4)と側面(5)との境界部分の
溶込みが充分に得られないことが多い0又、オシレート
が困難な狭開先では溶接そのものが難しい。The shape of the conventional non-consumable electrode is a five-cone shape as shown in FIGS. The result is as shown in FIG. That is, an arc (2) emitted from the tip of the electrode (1) generates a circular pool (3) directly below the mipole (1). In order to generate a bead over the entire width of the groove using such an electrode, it is necessary to oscillate, but sufficient penetration of the boundary between the bottom surface (4) and the side surface (5) of the groove can be obtained. Welding itself is difficult in narrow grooves where it is difficult to oscillate and where there are often no grooves.
本発明は上記実情に鑑み、電極下に広いプールが形成さ

〔問題点を解決する為の手段〕
本発明は、電極先端よりスリットを入れて少なくとも2
以上の尖端を゛形成せしめ、複数点よりおのおの特定方
向へアークを発生させる様にしたものである。In view of the above circumstances, the present invention is designed to form a wide pool under the electrode so that sufficient penetration can be obtained even in the above-mentioned boundary area, thereby achieving high performance and high quality even in narrow gap welding where oscillation is difficult. [Means for solving the problem] The present invention aims to provide a welding method that can perform welding.
The above-mentioned tips are formed so that arcs are generated from a plurality of points, each in a specific direction.
複数点よりアークが発生するので広幅の大プールが形成
され、オンレートしなくても広幅のビードが得られる。Since arcs are generated from multiple points, a large, wide pool is formed, and a wide bead can be obtained without on-rate.
以下図面を参照しつつ本発明の詳細な説明する。 The present invention will be described in detail below with reference to the drawings.
第1図(イ)(ロ)(ハ)、第2図は本発明の第1の実
施例を示している。FIGS. 1(A), 2(B), and 2(C) show a first embodiment of the present invention.
電極(1)の先端よりミ極軸心を含むスリット(6)を
所要の深さに刻設し、スリット(6)で分割された各部
分の先端を切出し状且点対称となる如く切削する。A slit (6) including the mipolar axis is carved at the required depth from the tip of the electrode (1), and the tips of each portion divided by the slit (6) are cut out in a cut-out shape and point symmetrical. .
斯かる電極(1)によってアークを発生させると電極の
各尖端(7G) (7b)よりアーク(2α)(2b)
が発生し偏平な大プール(3)が生成し、オシレートを
・しなくても前記した開先境界部分にアークを偏向さ
せて充分に溶込まずことができる(第2図)。When an arc is generated by such an electrode (1), an arc (2α) (2b) is generated from each tip of the electrode (7G) (7b).
This generates a large flat pool (3), and even without oscillation, the arc can be deflected to the groove boundary and not penetrate sufficiently (Figure 2).
又、該電極(1)を回転することにより溶接トーチを固
定したままでもオシレートしたと同様な効果が発揮され
、更に深い溶込みを達成することができる(第3図)0
以上本発明を広開光の溶接に実施すると、広幅のビード
が得られてパス数を減少し得溶接能率が向上し、狭開先
の溶接に実施すると従来困難であった狭開先溶接を安定
且確実に行うことができる。Furthermore, by rotating the electrode (1), even if the welding torch is fixed, the same effect as oscillation can be achieved, and even deeper penetration can be achieved (Fig. 3). When used for open welding, a wide bead can be obtained, reducing the number of passes and improving welding efficiency, and when used for narrow gap welding, it is possible to perform narrow gap welding stably and reliably, which was previously difficult. I can do it.

である。In the above embodiment, the slits are arranged in the shape of a single character, but it goes without saying that the slits may be arranged in the shape of a cross, and it is also possible to use mechanical oscillation, magnetic oscillation, etc. in combination with this method.
